Enso

Real-time waveform and LED motion for a wearable pain-relief device

Enso is an FDA-cleared, wearable device that delivers drug-free pain relief through proprietary electrical waveforms, controlled via the Hinge Health app. As the lead motion designer on the project, I was responsible for defining how those waveforms were experienced visually across both the app and the physical device itself.

On the software side, I designed a set of looping, interactive animations that visually correspond to Enso’s three patented waveforms. These animations needed to be expressive yet highly constrained, with adjustable parameters for speed, brightness, and pauses. We ultimately implemented them using Lottie, leveraging stroke width, scale, opacity, and timing to create a flexible system that could be programmatically tuned while remaining visually consistent. I worked closely with engineering to ensure the motion translated accurately into React Native and performed reliably in production.

In addition to the in-app experience, I designed the LED motion system on the device itself. This included defining animation behaviors for core states such as power on and off, pairing, active treatment, and system feedback. The goal was to create a clear, intuitive visual language that communicated device state at a glance while feeling calm, intentional, and aligned with the product’s therapeutic purpose. These LED animations had to balance clarity, battery efficiency, and hardware constraints, requiring close collaboration with engineering throughout development.
